Let's divide 2051951 by 558
The aim is to understand the frequency of 558 in 2051951.

Advancing to step 1:
If we divide 2 by 558, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 558

Advancing to step 2:
If we divide 20 by 558, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 558

Advancing to step 3:
205 divided by 558 is 0 with a remainder of 205.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 205 leaves us with 205.
Take the next digit (1) from the dividend and append it to 205, then repeat: 2051 / 558

Let's proceed to step 4:
When dividing 2051 by 558, we get 3 with a remainder of 377.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 1674 from 2051 leaves us with 377.
Bring next digit (9) of the dividend behind the 377 and repeat the process: 3779 / 558

On to step 5:
3779 divided by 558 is 6 with a remainder of 431.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we subtract 3348 from 3779, we get 431.
Take the next digit (5) from the dividend and append it to 431, then repeat: 4315 / 558

Moving on to step 6:
4315 divided by 558 is 7 with a remainder of 409.
Use 7 as the next digit of our solution. 
Result so far: 367.0
If we take 3906 away from 4315, we end up with 409.
Bring next digit (1) of the dividend behind the 409 and repeat the process: 4091 / 558

Step 7:
558 goes into 4091 7 times with a remainder of 185.
The number 7 becomes the next digit in our result. 
Result so far: 3677.0
Subtracting 3906 from 4091 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 8:
1850 divided by 558 is 3 with a remainder of 176.
Use 3 as the next digit of our solution. 
Result so far: 3677.3
Deduct 1674 from 1850 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 9:
558 can be fit into 1760 3 times, resulting in a remainder of 86.
The next digit of our result is 3. 
Result so far: 3677.33
If we take 1674 away from 1760, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

In conclusion, the division gives 3677.33 with a balance of 0.086.
